Hyperion.SerializerOptions exception

[jmnowick]

Trying to run the most basic example and I get an exception as follows.

"The type initializer for 'Hyperion.SerializerOptions' threw an exception."

running Akka 1.3.13 Akkling 0.93 which has Akka.Serialization.Hyperion 1.3.8-beta66 hyperion 0.98

1. Is that the entire exception message?
2. Are you sure that all packages and assemblies are in place? I remember that using nuget for resolving packages didn't load all dependecies (I think that Hyperion package itself was missing), however it works fine with Paket.

i met the same exception when i use akkling to creating the actor system. I have the same package version as @jmnowick . I use Visual Studio 2019 with dotnet core 3.0-preview-6

open Akka.FSharp
open Akkling

use system = Akka.FSharp.System.create "system-create" (Akka.FSharp.Configuration.load()) // 1. success
use system = Akka.FSharp.System.create "system-create" ( Configuration.defaultConfig() ) // 2. fail
use system = System.create "my-system" <| Configuration.defaultConfig() // 3. fail 

The exception of 2 and 3 are same below:

Update. If I target SDK to 2.2 everything works fine.
